RING FOR, RING-TWISTING FRAMES.

SPECIFICATION formingpart of Letters Patent No. 588,120, dated August 10, 1897. A li ation filed November 5,1896. Serial No. 611,143. (Nomad) To (LZZ wl'tont it ntagy cancer/t.-

Be it known that I, WALTER RIGBY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Rings and Travelers for Ring-Frames, of which the following is a full and complete specification,such as will enable those skilled'in the art to which it apper-' tains to make and use the same.

This invention relates to improvements in the ring and traveler for ring-frames for making twisted threads and yarns of all kinds; and the object thereof is to produce an improvement in this class of machines for preventing waste occasioned by the breaking of the thread or yarn in the process of twisting the same when winding it upon the spindles, a further object being to provide means for preventing the grease or oil by which the traveler-ring is lubricated from coming in contact with the thread or yarn as the latter is wound upon the spindles, and also for preventing the grease or oil from being thrown upon the floor or parts of the machine; and with these and other objects in view the invent-ion consists in the construction,combination,and arrangement of parts hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in whicl1- Figure 1 is a side view of a part of a thread or yarn twisting and winding machine, part of the construction being shown in section; and Fig. 2, a plan view of a part thereof.

In the drawings forming part of this specification the separate parts of my improvement are indicated by the same numerals of reference throughout the several views, and in said drawings I have shown at- 5 the vertically-movable ring-rail of a thread or yarn twisting and winding machine and at 6 two of the spindles, and it will be understood that any desired number of these spindles may be employed. These spindles are each provided with a head 7, at the lower end of which is a pulley 8, by which they are operated, and mounted on each of the spindles above the head 7 is a spool 9, and each of the heads is also provided with dowel-pins 10, which project upwardly into the spool and by means of which the latter is revolved with the spindle, all these features being of wellknown construction and form no part of this invention.

The vertically-movable ring-rail 5 is provided with the usual circular openings 11, which are much greater in diameter than. the spools; and in the practice of my invention I secure in each of said openings a circular band 12, which is provided with a, deep annular groove 13, and the outer wall of the annular groove 13 is less in height than the band 12, and mounted in the groove 13 and secured to the outer Wall 14 thereof is a traveler-ring 15, said traveler-ring being secured in position or to the outer wall of the groove 13 by a screw or screws 16, or in any desired manner.

There is a narrow annular space 17 between the traveler-rin g and the band 12, and mounted in this annular space and supported by the traveler-rin g is a traveler 18.

The traveler-ring and the traveler are substantially of the usual construction, said traveler-ri'n g being provided centrally of its outer side with an annular shoulder or projection 19, whereby it is secured to the outer wall of the annular groove 13, and the traveler 18 is provided at each end with hooks which overlap the upper and lower edges of the traveler- 7 ring, and in operation the material 20, from which the twisted thread of yarn is formed, is passed beneath the upper hook of the traveler'over the upper edge of the band 12 and connected with the spool 9.

I also provide means for lubricating the tra veler-ring and the traveler, which consists of a small perforation formed in'the outer wall 14 of the annular groove 13 and which passes through the traveler-ring, and the oil or lubricant is forced through this perforation and will be distributed over the entire inner surface 'of the traveler-ring by the traveler 18 in the operation thereof.

The operation of the device is the same as in all other machines of this class; but in machines of this class as heretofore constructed there has been noguard between 4 ment.

, knots therein.

and thus cause considerable loss. My invention also serves to an extent to prevent the frequent breaking of the thread or yarn and therefore avoids the necessity of forming It is also a well-known fact that When in the operation of these machines the thread or yarn which is connected with one of the spools breaks the said thread or yarn will come in contact with the traveler or traveler-ring as the spool or spindle revolves and will be thrown off and into contact with the adjacent spool or spindle, and thus grease or injure the thread on said ad jacent spool or spindle, thus causing great inconvenience and loss, and this result is also prevented to an extent by my improve- The traveler-ring and traveler will also be better lubricated and the throwing of the oil or lubricant upon the floor or parts of the machine by the rapid revolution of the spools or spindles will also be prevented, and with my improvement-it is not necessary to stop the machine in order to lubricate the traveler-ring and traveler, and the ring and traveler can be oiled as well when the machine is in operation as when it is not, and a single operator can run more spindles than with machines of this class as usually constructed.

The annular band 12 is preferably projected slightly above the traveler-ring, as is clearly shown in the drawings, but it will be apparent that changes in and modifications of the construction herein described may be made without departing from the spirit of my invention or sacrificing itsadvantages.

Having fully described my invention, I claim as new and desire to secure by Letters Patent- The combination in a machine of the character described, of a ring-rail provided with a circular opening, a circular band resting upon the rail and fitting in the opening, and which is provided with a deep annular. groove a traveler-ring secured to the outer wall of said groove by screws, and provided with an oil-hole extending through said band and ring,

said band and said ring leaving a narrow annular space 17 between them, said ring being provided on its inside with annular shoulders or projections, one projecting upward and the other downward, and a traveler provided with hooks adapted to embrace the upper and lower edges of the said ring and travel in the said annular space, substantially as and for the purpose set forth.

In testimony that I claim .the foregoing as my in vention'I have signed my name, in presence of the subscribing witnesses, this 30th day of October, 1896.
